IMPROVEMENT IN KEROSEN E-LAM PS.

Specification forming part of Letters Patent No. 38,208. dated April 21, 1863.

To all whom it may concern:

Beit known that we, SAMUEL ADLAM, J r., and J. R. FOGG, of the city of Portland, in the county of Cumberland and State of Maine, have invented a new and useful Improvement in Glass Chimney Attachments for Kerosene- Lamps 5 and we do hereby declare the following to be a full and exact description thereof, reference being had to the accompanying drawings, forming part of this our specificat'on, and to the letters of reference marked thereon, like letters in the several figures indicating the same parts, and in which drawrugs- Figure 1 is a sectional view of the glass chimney, the metallic cone, and metallic cap of a kerosene-burner, as ordinarily constructed; and Fig. 2 a side view of the metallic cap shown in Fig. 1, the cap being detached from the lamp. Fig. 3 is a vertical section of my glass chimney attachment applied to the ordinary kerosene-burner, as shown in Fig. 1; Fig. 4., a plan View of the same with the cone and cone-plate swung around to one side of the burner-cap and away from its position over the wick-tube, as shown in black lines in Fig. 3; Fig. 5, a plan view of the cone and cone-plate, and showing the means of securin g the glass chimney thereto; and Fig. 6, a side view of the same, attached 81 as to articulate upon a metal band.

,The object of our invention is to provide the means whereby a kerosene-burner, as now ordinarily constructed, in which the glass chimney can only be removed from the lamp for the purpose of trimming and lighting the wick, by claspin g the chimney with the fingers and so detaching it, may readily and cheaply be converted into a lamp of that class of kerosene-burners which admits of a removal of its glass chimney without causing the fingers to come in contact with the chimney or detaching it from the lamp.

In the drawings, A indicates the stand of alamp, terminating at its upper portion in an oil-reservoir, B, upon the neck of which a metallic cap, 0, is cemented in the usual manner, all as shown in Fig. 1. The cap 0,

at its upper extremity, is formed into a series of projections, 61, clearly shown in Fig. 2, and, just beneath them, as at e, the diameter of the cap is reduced so as to form a shoulder upon which to receive the base of a cone, f. One

or more of the projections 61, as seen at d,Fig.

1, are bent over inwardly so to snugly clasp the base flange d of. the glass chimney 9,

when occupying the position indicated in said figure, a metal spring, as at h, beingalso arranged, as indicated in the figure, so as to fingers or hand of the operator, and in doing which,-if the chimney should happen to behot, often results either in burning the hand or breaking the chimney. To obviate such difficulty, and at the same time convert the kerosene-burner just described into a lamp of that class which admits of a removal of its glass chimney without necessitating a contact of the hand with it, or its detachment from the lamp, and yet, at the same time, utilize all the main portions of the ordinary keroseneburner which we have described, is, as before stated, the object of our invention. To effect this we construct a cylindric band, as seen in section in Fig. 3 and in side view, Fig. 5, of a diameter to snugly fit within the cap 0. This band D is made of metal, and is provided with oblong openings 1', cut through its sides, as shown. At its upper edge it is provided with an arm, k, which supports a cone, 1, and perforated cone-plate l, the latter being pivoted to the arm 70, as indicated at x in Figs. 3, 4, and 6. Lips or curved projections m are formed on the periphery of the cone plate 1 to embrace the flange at the base of a glass chimney when placed thereon, and a set-screw device, as at E, is made to secure the chimney in place, as indicatcdin red lines in Fig. 3. We also cut a recess or notch, p, in the edge of the cone-plate Z, as clearly seen in Fig. 4, which notch will receive the spring h and retain the said plate in position, as represented in Figs. 3 and 5, when the cone-plate is turned back from the position it occupies in red lines in Fig. 3 to that occupied by it as shown in black lines in said last-named figure.

Having completed a band, D, with its attachments as figured and described, and desiring to convert the ordinary lamp, as represented in Fig. 1, into the improved lamp, as

represented in Fi g. 3, we proceed as follows "We first remove the glass chimney from the position it occupies in Fig. 1 and secure it to the cone-plate l, as represented in Fig. 3. Te then remove the cone f from the cap 0, and manipulate the spi ing h from the form and position shown in Fig. 1 into the form and position shown in Fig. 3. We then insertthe metal band D into the burnercap 0 until the bottom of the band rests upon the shoulder e of the cap, whereupon we turn or bend two or more of the projections d of the cap 0 into and through the oblong openings or slots 6 of the band D, and so without any soldering or brazing firmly secure the band in permanent position within the cap. The operation is thus completed, and the old style, ordinary coa1-oil burner, as seen in Fig. 1, is converted into the new and improved style of coal-oil burners as shown in Fig. 3, and with only the loss of a single partto wit, the conef.

It is obvious that when a lamp organized asshown in Fig. 3 needs trimming, access will be given to the wick by merely withdrawing the spring h from the notch 77, and then causing the cone 1 and cone-plate Z, with the glass chimney thereon, to swing around into the position shown in red by the'pressui e of the finger upon the set-screw device E. It is also obvious that when the glass chimney is swung back from the position in red to that in black in Fig. 3, the spring It will be pressed outwardly by contact with the edge ,of the cone-plate until the recess or notch p registers with the spring h, at which'moment the spring h will automatically enter the notch and so hold the chimney, cone, and coneplate in proper position upon the lamp and over the wick. It is also evident that our device may be used by simply cementing the band D directly to the neck of the lamp.

Having thus described our invention, what we claim as new, and desire to secure byLetters Patent of the United States, is-

The band D, in combination with the pivoted cone-plate Z and cap 0, substantially in the manner and for the purpose set forth.
